This is the second year I've tried to grow pumpkins, and no luck. The plants look healthy enough each year, they get large yellow flowers that bloom every morning, and I see bees in my yard. But for the second year in a row, not a single pumpkin has grown. I even tried planting a different variety of seed this year, and still no luck. Any ideas? But I doubt I'll try again next year. I'd rather use all that garden space for something I know will grow.
